Ah, I hadn't gotten to casts yet with my test framework.
I'm certainly open to suggestions on how to address this, but I will
point out that we already have a number of cases where we issue
additional queries against the database from the dump*() functions when
we need to collect additional information. That's not wonderful because
it ends up being slow, but it does work.
Trying to figure out what functions we need at getFuncs() time isn't
terribly easy. On the other hand, it might not be *that* bad to just
pull in all functions, if we use the same technique that we use for
tables, and mark the ones we aren't dumping as not "interesting."
Thanks!
Stephen
